Bei einer Schweißvorrichtung zum Verschweißen von Folienmaterial werden zwei oder mehrere Folien einer Schweißeinrichtung zugeführt und dort mit Hilfe eines Schweißkopfes, der auf die zusammengelegten Folien abgesenkt wird und an gewünschten Stellen Hitze auf die Folien überträgt, miteinander verschweißt. Wenn in dem vorliegenden Text von Schweißen bzw. Schweißeinrichtung die Rede ist, so ist damit auch ein Heißklebeprozeß mit umfaßt, bei welchem ein Klebematerial zwischen die Folien gebracht wird, das durch Hitze zur Verbindung der Folienmaterialien führt.In a welding device for welding foil material, two or fed several foils to a welding device and there using a Welding head, which is lowered onto the folded foils and at desired Place heat transferred to the foils, welded together.

Ein derartiger Schweißprozeß wird z.B. bei der Herstellung von Folienbeuteln, z.B.
Getränkefolienbeuteln, eingesetzt Zwei Folienmaterialien werden aufeinandergelegt,
die die Seitenfolien des Folienbeutels bilden sollen. In einem Kantenbereich wird ggf.
eine Bodenfolie dazwischengelegt. An zwei direkt aufeinanderliegenden Kanten des
Seitenfolienmaterials und an der dritten Kante, an der sich ggf. die Bodenfolie befindet,
werden die Folien miteinander verschweißt Die vierte Kante der jeweiligen Folienmaterialien
wird nach der Füllung des Folienbeutels durch Verschweißen verschlossen.
Ein Beispiel eines solchen Folienbeutels ist z.B. in Figur 3 gezeigt, wobei
die Schweißnähte 33 in dem ersten geschilderten Prozeß gebildet werden und die
Schweißnaht 34 nach der Füllung des Folienbeutels.Such a welding process is e.g. in the manufacture of foil bags, e.g.
Beverage foil bags, inserted Two foil materials are placed on top of each other,
which should form the side foils of the foil pouch. In an edge area,
put a bottom sheet in between. On two edges of the
Side film material and on the third edge, where the bottom film may be,

In einer automatisierten Fertigungsanlage werden Folienstränge zum Verschweißen zugeführt, die nach dem Schweißvorgang zerschnitten werden, um einzelne Einheiten zu bilden. Die Folienstränge werden zusammengelegt und unter den Schweißkopf geführt. Dieser senkt sich ab. Dabei muß er einen mehrere Zentimeter umfassenden Absenkweg überbrücken. Nach dem Aufdrücken auf die Folienmaterialien hebt sich der Schweißkopf wieder und die Folienstränge werden um eine einem Folienbeutel entsprechenden Strecke weiterbewegt, bevor sich der Schweißkopf wiederum auf das weiterbewegte Folienmaterial absenkt Um einen hohen Durchsatz zu gewährleisten, wird der Schweißkopf auf einer konstant hohen Temperatur gehalten, um zeitraubende Aufwärm- und Abkühlvorgänge überflüssig zu machen. Daher ist es nötig, daß der Schweißkopf in den Betriebszuständen, in denen keine Schweißung stattfindet, weit genug von dem Folienmaterial entfernt ist, um ein Überhitzen bzw. Verschmoren des Folienmateriales zu verhindern. Dies ist z.B. nötig, wenn die gesamte Schweißvorrichtung angehalten worden ist, um eine Fehlfunktion zu beseitigen.In an automated production line, film strands are used for welding fed, which are cut after welding to individual units to build. The foil strands are put together and under the welding head guided. This lowers. He must have a several centimeters Bridge the lowering path.

Die erfindungsgemäße Schweißvorrichtung kann mindestens drei Betriebsstellungen einnehmen. Die erste Betriebsstellung ist die Schweißstellung zur Durchführung der Folienverschweißung. In diesem Betriebszustand befindet sich der Schweißkopf direkt auf den zu verschweißenden Folienmaterialien und führt zu der Erhitzung und Verschweißung bzw. Heißverklebung der Folienmaterialien in jenen Bereichen, auf denen die erhitzte Fläche des Schweißkopfes aufliegt. Die zweite Betriebsstellung ist eine Zwischenstellung, in der der Schweißkopf einen ersten vorgegebenen Abstand von der Schweißstellung hat.

Die erfindungsgemäße Schweißvorrichtung ermöglicht also einen kurzen Hub- bzw. Absenkvorgang zwischen der Schweißstellung und der Zwischenstellung, so daß im Normalbetrieb diese Bewegung des Schweißkopfes zu keinem Zeitverlust führt, auch wenn die gesamte Schweißvorrichtung mit hoher Geschwindigkeit betrieben wird. Im Falle einer Fehlfunktion oder bei geringer Geschwindigkeit der gesamten Anlage nimmt der Schweißkopf eine Ruhestellung ein, die einen größeren Abstand von dem Folienmaterial hat, so daß eine Schädigung des Folienmateriales durch den heißen Schweißkopf vermieden wird.The welding device according to the invention thus enables a short lifting or Lowering process between the welding position and the intermediate position, so that in Normal operation this movement of the welding head does not result in loss of time, too when the entire welding device is operated at high speed. in the In the event of a malfunction or if the entire system is slow the welding head takes a rest position which is a greater distance from that Has film material, so that damage to the film material by the hot Welding head is avoided.
Der Abstand der Ruhestellung von der Schweißstellung kann so gewählt sein, daß eine Schädigung, z.B. ein Verschmoren, des Folienmateriales durch die Hitze des Schweißkopfes deutlich verzögert wird. In besonders vorteilhafter Ausgestaltung wird der Abstand der Ruhestellung und der Schweißstellung jedoch so gewählt, daß überhaupt keine Zerstörung des Folienmateriales durch die Hitze des Schweißkopfes auftreten kann. Auf diese Weise ist gesichert, daß unabhängig von der Dauer der Unterbrechung bzw. Verlangsamung des Betriebes der Schweißvorrichtung keine Schädigung des Folienmateriales auftreten kann.The distance between the rest position and the welding position can be chosen such that damage, e.g. a scorching of the film material by the heat of the Welding head is significantly delayed. In a particularly advantageous embodiment the distance between the rest position and the welding position, however, chosen so that at all no destruction of the foil material by the heat of the welding head can occur. In this way it is ensured that regardless of the duration of the No interruption or slowdown in the operation of the welding device Damage to the film material can occur.
Eine besonders vorteilhafte Ausgestaltungsform umfaßt eine Wärmeabschirmung, die in der Ruhestellung zwischen den heißen Schweißkopf und das Folienmaterial gebracht wird. Speziell bei besonders temperaturempfindlichen Folienmaterialien sichert eine solche zusätzliche Abschirmung, daß das Folienmaterial durch die Hitze des Schweißkopfes nicht geschädigt wird. Eine solche Wärmeabschirmung kann z.B. ein schwenkbares Abschirmblech umfassen.A particularly advantageous embodiment comprises a heat shield, the one in the rest position between the hot welding head and the foil material brought. Secures especially with particularly temperature sensitive film materials such additional shielding that the film material by the heat the welding head is not damaged. Such a heat shield can e.g. comprise a pivotable shielding plate.
Günstige Werte für den Abstand der Ruhestellung von der Schweißstellung liegen im Bereich einiger Zentimeter. Dieser Abstand ist im wesentlichen von der Art des verwendeten Folienmateriales, der Schweißtemperatur sowie der Geometrie des verwendeten Schweißwerkzeuges abhängig. Vorteilhafterweise wird für den Abstand der Schweißstellung zu der Zwischenstellung ein Abstand von einigen Millimetern gewählt Ein so geringer Abstand gewährleistet eine hohe Durchsatzgeschwindigkeit aufgrund des geringen Hubweges.Favorable values for the distance between the rest position and the welding position are in the Range of a few centimeters. This distance is essentially dependent on the type of used Foil material, the welding temperature and the geometry of the used Welding tool dependent. Advantageously, for the distance Welding position to the intermediate position selected a distance of a few millimeters Such a small distance ensures a high throughput speed due to the short stroke.
Auf einfache Weise läßt sich die Bewegung des Schweißkopfes zwischen der Zwischenstellung und der Schweißstellung mit Hilfe einer ersten Pneumatik erreichen. Aufgrund des geringen Abstandes, der zu überwinden ist, benötigt die Pneumatik nur sehr wenig Druckluft. Eine zweite Pneumatik wird eingesetzt, um den Schweißkopf zusammen mit der ersten Pneumatik in die Ruhestellung zu bewegen.In simple Way the movement of the welding head between the intermediate position and reach the welding position with the help of a first pneumatics. by virtue of Because of the small distance that has to be covered, the pneumatics require very little Compressed air. A second set of pneumatics is used around the welding head to move to the rest position together with the first pneumatics.
Die Bewegung des Schweißkopfes und des dazugehörigen Antriebes kann z.B. mechanisch ausgelöst werden. Eine zuverlässige Realisierung wird durch eine Steuerung dargestellt, mit deren Hilfe die Fördereinrichtung zur Weiterförderung des Folienmateriales angesteuert wird, während der Schweißkopf sich in der Zwischenstellung befindet.The movement of the welding head and the associated drive can e.g. mechanically to be triggered. A control system ensures a reliable implementation shown, with the help of the conveyor for the further promotion of the film material is controlled while the welding head is in the intermediate position located.

verschweißte Folienmaterial 30 liegen dabei auf einer Auflage 20 auf. Der Abstand
des Schweißkopfes 24 von der Pneumatik 26 beträgt D, wobei D größer ist als der
Abstand B, den der Schweißkopf 24 von der ersten Pneumatik 26 in der Zwischenbzw.
Ruhestellung einnimmt.Figure 2c shows the same welding device in the welding position. The
Das erfindungsgemäße Verfahren wird nun am Betrieb der gezeigten Ausführungsform
der erfindungsgemäßen Schweißvorrichtung erläutert. Die Folienmaterialien 2
und 4 werden von den Vorratsrollen 6 und 8 abgezogen, wobei eine ausreichende
Spannung auf hier nicht interessierende Weise z.B. durch federbeaufschlagte
Spannvorrichtungen 10 und 12 aufrechterhalten wird. Umlenkrollen 14 und 16 führen
die Folienmaterialien zusammen. Die zu verschweißenden Folienmaterialien 2 und 4
werden dabei mit Hilfe der Abzugswalzen 18 taktweise bewegt. Die während eines
Taktes zurückgelegte Strecke entspricht dabei der Breite eines Folienbeutels 32.
Während der Bewegung des Folienmateriales 2, 4 bzw. des verschweißten Folienmateriales
30 in Richtung 22 befindet sich der Schweißkopf 24 in einem Abstand y von
dem Folienmaterial (s. Figur 2b). Sobald die Bewegung der Abzugswalzen 18 durch
die Steuerung 38 gestoppt wird, gibt die Steuerung 38 ein Signal an die erste Pneumatik
26, woraufhin der Abstand B des Schweißkopfes 24 von dieser Pneumatik 26
auf den Abstand D vergrößert wird (s. Figur 2c). Der Schweißkopf 24 befindet sich
nun in direktem Kontakt mit dem zu verschweißenden Folienmaterial 2, 4 und drückt
dieses gegen die Auflage 20. Er weist in an sich bekannter Weise ausreichend erhitzte
Bereiche auf, die zu einer Verschweißung des Folienmateriales entlang der gewünschten
Schweißnähte führt. Diese Schweißnähte bilden bei dem Beispiel der Folienbeutel
(Figur 3) später die Seitenkanten bzw. die Bodenkanten 33. The method according to the invention will now operate on the embodiment shown
of the welding device according to the invention explained. The
Ist die Verschweißung entlang der gewünschten Schweißnähte durchgeführt, wobei
die dazu notwendige Zeitdauer im Vorhinein bestimmt werden kann, gibt die Steuerung
38 ein Signal an die erste Pneumatik 26 den Schweißkopf 24 wieder anzuheben,
so daß der Abstand des Schweißkopfes 24 von der Pneumatik 26 wieder B
beträgt. Der Schweißkopf 24 befindet sich dann wieder in der Zwischenstellung.
Gleichzeitig gibt die Steuerung 38 ein Signal an die Abzugswalzen 18, das Folienmaterial
um eine Einheit, z.B. die Breite eines Folienbeutels 32, weiterzubewegen. Nach
Abschluß dieser Bewegung gibt die Steuerung 38 wieder ein Stoppsignal an die Abzugswalzen
18 und ein Signal an die Pneumatik 26, den Abstand des Schweißkopfes
24 von der Pneumatik 26 wieder von B auf D zu erhöhen. Durch entsprechende
Wiederholung der Vorgänge entsteht ein taktweiser Betrieb, der eine hohe Durchsatzleistung
ermöglicht, da der Schweißkopf 24 immer nur um den kleinen Abstand y,
z.B. einige Millimeter, bewegt werden muß. Die geringe zu überwindende Höhe y benötigt
auch nur eine kleine Druckluftmenge zum Betrieb der Pneumatik 26.Is the welding carried out along the desired welds, where
the controller specifies the time required for this in advance
38 a signal to the
Aus verschiedenen Gründen kann es nötig sein, den taktweisen Betrieb der gesamten
Schweißvorrichtung zu unterbrechen. Dies ist z.B. bei Wartungsarbeiten, Kontrollvorgängen
oder bei der Behebung einer Fehlfunktion notwendig. Während dieser
Zeit ist es nicht immer notwendig, die Heizung des Schweißkopfes 24 abzuschalten.
Dies wäre aus energiespartechnischen Gründen und aus Gründen der Zeitersparnis
ungünstig, da ein Wiederaufwärmen des Schweißkopfes eine große Energie benötigt
und lange dauert. Während des Stillstandes der Folienweiterförderung besteht jedoch
die Gefahr der Überhitzung des Folienmateriales durch den heißen Schweißkopf.For various reasons, it may be necessary to run the entire cycle
Interrupt the welding device. This is e.g. during maintenance work, control processes
or necessary to correct a malfunction. During this
Time it is not always necessary to switch off the heating of the
Um eine dadurch mögliche Schädigung des Folienmateriales zu vermeiden, gibt die
Steuerung 38 ein Signal an die zweite Pneumatik 28, wenn der Betrieb der gesamten
Schweißvorrichtung unterbrochen wird. Ein solches Signal kann z.B. direkt ausgelöst
werden, wenn eine Bedienungsperson die Förderung des Folienmateriales
stoppt, oder automatisch ausgelöst werden, wenn die Folienförderung über einen
vorbestimmten Zeitraum stillsteht. In order to avoid possible damage to the film material, the
Das Signal an die zweite Pneumatik 28 löst eine Verringerung des Abstandes C der
ersten Pneumatik 26 von der zweiten Pneumatik 28 auf einen Abstand A aus (s. Figur
2a). Auf diese Weise wird der Abstand x des Schweißkopfes 24 von dem Folienmaterial
2, 4 bzw. 30 vergrößert, z.B. auf einige Zentimeter. So ist eine Schädigung
des Folienmateriales durch die Hitze des Schweißkopfes 24 ausgeschlossen.The signal to the
Wird besonders temperaturempfindliches Folienmaterial verarbeitet, so kann zusätzlich
ein Abschirmblech vorgesehen sein, das gleichzeitig mit der Aktivierung der
zweiten Pneumatik 28 zwischen den Schweißkopf und das Folienmaterial geschwenkt
wird, um die Wärme des heißen Schweißkopfes 24 von dem Folienmaterial
abzuhalten. Wird der Schweißkopf 24 wieder aus der Ruhestellung abgesenkt, so
wird gleichzeitig auch das Abschirmblech wieder weggeschwenkt.If particularly temperature-sensitive film material is processed, it can also be used
a shielding plate may be provided, which at the same time the activation of the
Bei dem vorliegenden Ausführungsbeispiel werden die Folienmaterialien 2 und 4 zur
Bildung der Seitenfolien eines Folienbeutels 32 eingesetzt. In den Figuren 1 und 2 ist
der Übersichtlichkeit halber die dritte Zuführeinrichtung für das Folienmaterial der Bodenfolie
nicht gezeigt, welches zwischen die Folienmaterialien 2 und 4 gelegt wird
und gleichzeitig durch die Schweißeinrichtung 36 mit verschweißt wird.In the present embodiment, the
Abweichend von der Form der Folienbeutel, die bei dem beschriebenen Ausführungsbeispiel verarbeitet werden, kann die erfindungsgemäße Vorrichtung auch zur Verarbeitung von Folienbeuteln eingesetzt werden, bei denen die Seitenfolien ohne eine zusätzliche Bodenfolie direkt miteinander verschweißt werden. Dann ist eine dritte Zuführeinrichtung für Folienmaterial nicht notwendig.Deviating from the shape of the foil bag, which in the described embodiment processed, the device according to the invention can also be used for Processing of foil bags are used in which the side foils without an additional base film can be welded directly to one another. Then there is one third feed device for film material is not necessary.
Beschrieben ist eine Vorrichtung, die die Folien direkt miteinander verschweißt. Bei
entsprechender Auswahl eines Klebemittels kann auch eine Heißverklebung bzw.
eine Heißverschweißung mit der Schweißeinrichtung 36 durchgeführt werden.A device is described which directly welds the foils together. at
Appropriate selection of an adhesive can also be hot glued or
a hot welding can be carried out with the
Die Steuerung 38 kann so ausgestaltet sein, daß nicht nur bei einer Unterbrechung
der Folienförderung die Ruhestellung gemäß der Figur 2a eingenommen wird. Vielmehr
kann die Steuerung 38 auch so ausgestaltet sein, daß bei einem langsam gewählten
Takt der Abzugswalzen 18 der Schweißkopf 24 während der Weiterförderung
des Folienmateriales nicht die Zwischenstellung einnimmt, sondern die Ruhestellung,
die in Figur 2a gezeigt ist. Dazu kann eine Eingabemöglichkeit an der Steuerung vorgesehen
sein, mit deren Hilfe eine Bedienungsperson einen Mindesttakt angeben
kann, bei welchem während der Folienweiterförderung nur die Zwischenstellung gemäß
der Figur 2b eingenommen wird und nicht die Ruhestellung gemäß der Figur 2a.The
Die Schweißeinrichtung 36 der beschriebenen Ausführungsform realisiert die verschiedenen
Stellungen des Schweißkopfes mit Hilfe zweier in Serie geschalteter
Pneumatiken.The
